Specification of Letters Patent.

Patented Dec. 23, 1913.

Application filed March 29, 1913. Serial No. 757.580.

To all whom it may concern Be it known that I, KNU'r Jonas ELIAS llnssnmlAN, a citizen of the Kingdom of Sweden, residing at Saltsjii-Storiingen.

Stockholm, Sweden, have invented new and useful Improvements in Vaporizers for luterntil-Combustion Engines, of which the following is a specification.

My present invention pertains to vaporizers for internal combustion engines, and is designed more particularly as an improvement on the vaporizer disclosed in my Letters-Patent No. 910,534 of January 9.6, 1909.

The present. invention will be fully understood from the following description and claim when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a longitudinal section of my novel vaporizer. Fig. 2 is a side elevation of the same.

Similar numerals of reference designate corresponding parts in both views of the drawings.

In a vaporizer of the ty e disclosed in my patent aforesaid, liquid uel is introduced through a channel 2 into the annular fuel supply channel 3 provided in the body 1 and is during the pump strokes forced up into the fuel chamber 5 through upwardlydirected ports and is thereupon carried with air or gas under pressure through the channels S to the space around the valve body 10. The chamber 5 is by means of projections 1' on the body 1 divided in a plurality of pockets each of which communicates wlth one of said channels 8.-

I have found that this vaporizer does not work reliably when it is used in high speed combustion engines. This is due to the circumstance that the fuel forced through the upwardly-directed ports at a comparatively high velocity has no time to come into rest in the pockets between the projections 1 before the introduction of the fuel into the cylinder of the engine commences and on account thereof it happens that the air or gas under pressure carries with it a part only of the fuel forced up into the pockets. In order to remove the said inconvenience the upwardly directed ports 15 according to the present invention have laterally directed arms at their upper ends with a view to assuring the fuel forced through said ports settling promptly and easily on the bottoms of the pockets. When so discharged into the pockets an adequate quantity of the liquid fuel will always be carried with the air or gas under pressure, and the efficiency of the vaporizer will be increased. It will also be noticed that in the improved construction the bottoms of the pockets formed by the projections 1 in the chamber 5 are closed.

Having described my invention, what I claim and desire to secure by Letters-Patent, 1s:

A vaporizer of the type described, comprising a body 1 havin a liquid-fuel supply channel 3 and a liquic -fuel chamber 5, the latter divided by projections on the body into pockets and the pockets being closed at their lower ends, and also having upwardlydirected ports connecting said channel 3 and chamber 5; said ports being formed in said projections and being provided with upper laterally-directed portions arranged to discharge into the pockets.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
